So, I was going to make a rocket style camp-stove out of a "#10" tomato can, but I ended up with another can "eggplant" that's got a rather interesting shape.I can't decide how I want to use the "eggplant", and getting another one involves a 2hr trip to get to the store I found it at.

The "#10" won't fit on top as the rolled rims are the same size, but the "eggplant" will sit perfectly down inside the "#10" and the lid from opening the "#10" will fit right on the inner rim from the pull-tab of the "eggplant".Could I get some suggestions or recommendations?I'm also not certain about the label on the "eggplant", it looks like it's shrink-wrapped on but it's actually painted like soda bottles are.
